Need info please from those more experienced w/ GS pedigrees. I was told by a breeder that they are no longer using KKl 1 or 2 but just AK or passed? Is this true & when did this change occur? What does AK stand for? KKl 1 used to mean preferred for breeding & a 2 meant they could still breed but that there was some fault to watch out for. What does this AK & "passed" really mean? The dog in question was born 12/28/2011. When did the nomenclature change? Thanks for any help you can provide.
